Abstract
Systems and methods include processing circuitry including one or more memory devices coupled to one or more processors, the one or more memory devices configured to store instructions thereon, the instructions when executed by the one or more processors, and the one or more memory devices configured to store instructions on the one or more processors. The controller is configured to cause the one or more processors to receive temperature information indicative of a temperature within the air inlet, to receive humidity information indicative of an inlet air humidity at the air inlet, to receive pressure information indicative of an air pressure within the air inlet, to determine a dew point temperature limit based on the temperature information, the humidity information, and the pressure information, to determine an exhaust emission output, and to output the exhaust emission output. A liquid flow is determined based on the dew point temperature limit, the liquid flow reducing the exhaust emission output, and at least one of the pump or the valve is controlled to provide the liquid flow.
